(A)
The compost quality standards in this
paragraph are applicable to all compost produced from yard waste, animal waste,
agricultural waste, food scraps, and alternative materials. The owner or
operator shall have the samples collected pursuant to rule
3745-560-125 of the
Administrative Code analyzed to demonstrate that concentration limits are not
exceeded for the parameters listed in the following tables:

TMECC 03.08

Method for determining percent foreign matter.

Foreign matter content shall be determined by passing a dried,
weighed sample of not less than one hundred grams of compost through a U.S.
standard No. 5 sieve (four millimeter). The material remaining on the screen
shall be inspected and the foreign matter shall be separated and weighed. The
weight of the foreign matter divided by the total weight of the compost sample
and multiplied by one hundred shall be the per cent dry weight of the foreign
matter content.

[Comment: The parameters identified for testing in table 4 have
no associated concentration limits. The analysis is necessary to ensure that
compost quality is appropriate for the recipient's specific use of the compost
product.

Acceptable levels of maturity will vary according to end-user
application (note: check date of maturity test).

Acceptable pH level will vary according to end-user application
and will generally be in the 5.5 - 8.5 range.

Acceptable levels of soluble salts will vary according to
end-user applications. The optimal ranges for growing media (compost amended
soil) is 0.5 to 4.5 millimho per centimeter.

(B)
Supplementary compost quality standards. Additional information or testing of
feedstocks, bulking agents, additives, compost, or compost product may be
required to ensure the standards are appropriately protective of public health
or safety or the environment.

(1)
Upon written
notification by the director, the owner or operator shall provide information
regarding the feedstocks, bulking agents, additives, compost, or compost
product including but not limited to the following:

(a)
A description of the agricultural,
industrial, or commercial process used to produce the feedstock, bulking
agents, additives, compost, or compost product.

(c)
A
description of any known or potential heavy metals and organic compounds that
may threaten to cause an adverse effect to public health or safety or the
environment.

(2)
Upon
written notification by the director, the owner or operator shall sample and
test for additional parameters as deemed necessary to ensure the standards are
appropriately protective of public health and safety and the
environment.

(3)
Upon review of
such additional information, the director may establish additional conditions
or quality standards for the compost. The director shall provide written
notification to the owner or operator of such conditions or standards.

[Comment: Compost containing mixed solid waste does not have
testing parameters as it may only be distributed in accordance with paragraph
(A)(1) of rule
3745-560-120 of the
Administrative Code.]
